Atomistic-Continuum Coupling by Homogenization
Aagashram Neelakandan, Karsten Albe, Bernhard Eidel
Classical atomistic simulations based on interatomic potentials resolve lattice instabilities, defect nucleation, and microstructure evolution with high fidelity, but their accessi…
Accurate Nanoscale Mapping of Electric Fields across Random Grain Boundaries in Polycrystalline Oxides Using Precession-Assisted 4D-STEM
Sangjun Kang, Hyeyoung Cho, Maximilian Töllner +12
Space charge layers (SCLs) at grain boundaries play a crucial role in modulating local electric fields and influencing the functional properties of materials, such as oxygen vacanc…
Impact of charge transition levels on grain boundary properties in acceptor doped oxide ceramics: A phase-field study
Kai Wang, Sangjun Kang, Mahmoud Serour +8
Advanced doping strategies enable oxide ceramic functionalities by tailoring bulk defect chemistry and space-charge-layer (SCL) behavior at interfaces. Charge transition levels (CT…
